Original application filed February 25, 1909, Serial No. 479,937. Divided and this application filed February 25, 1910. Serial No. 545,906.

To all whom it may concern:

Be it known that I, Mrr'rs QUENNER, a citizen of the United States, residing at Santa Ana, Sonora, Mexico, have invented certain new and useful Improvements in Separators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in separators and has for its object the provision of a machine primarily designed for the treatment of pulverized metal bearing material in a dry state, to recover precious metals, etc., although it will be apparent to those skilled in the art that the machine is capable of other similar uses.

My improved separator is adapted for use alone, or as an ancillary feature of a combined crusher or pulverizer and separator, as illustrated for example in my copending application Serial No. 17 9,937, filed Feb. 25, 1909, of which latter application the present case is a division.

Important features of a convenient embodiment of the invention comprise a supporting surface, preferably inclined, formed of foraminated material over which the pulverized material is fed, in combination with means for forcing air upwardly through the foraminated support and material thereon, and receiving pockets arranged in operative relation to the support and opening to the apertures therein from therebeneath; and preferably means for positively ejecting the accumulated precious metals, etc, from said receiving pockets.

The novel details in the construction and arrangement of parts of the separator will be apparent from the detailed description and claims hereinafter contained when read in connection with the accompanying drawings forming part hereof and wherein the before mentioned convenient embodiment of the invention is illustrated.

In the drawings: Figure 1 is a side elevation of the separator, Fig. 2 is a longitudinal sectional view of the same, and Fig. 3 is a transverse section taken on a line through one of the receiving pockets.

Referrin more specifically to the drawings wherein like reference characters designate corresponding parts in the several views, 26 represents a suitable box or casing treated and the predetermined capacity of the machine. This casing is open at its bottom, being connected around its marginal portions with a bellows 27. I

25 are supporting legs for the casing 26, the legs at the feed end of the device being longer than those at the discharge end to give a proper inclination to the supporting or upper surface 34 of the casing, the latter being formed of foraminated material and provided with rifiles 35 arranged transversely thereof and at suitable distances apart.

The bellows is operated by means of pitmen 28 connected to cranks 29 mounted to rotate with a transverse shaft 30, thelatter being journaled in bearings at the feed end of the box or casing 26. This shaft 30 may be driven in any desired manner, conveniently through the means of a sprocket chain 31 driven from any suitable source of power engaging a sprocket 31 on the shaft 30.

The inclined box or casing 26 is provided with a series of air inlet openings 32 covered by inwardly opening valves 33 conveniently of a flat type covered with canvas, or of any other desired type or construction. These valves open and close in consonance with the operation of the bellows, as is apparent. In the expanding movement of the bellows the valves open and the bellows and box are charged with air, while in the contracting movement of the bellows, said .air is forced upwardly through the supporting screen 34 and through the material thereon. As the particles pass downwardly over the upper surface of the sup porting screen 34, they are met by the currents of air and engage the riifies 35.

In advance of each riffle 35 there is a transversely arranged tube 36 supported within the box or casing immediately below the screen and having an open communication throughout the length of the tube with the apertures in the supporting screen leading through the latter to the material thereabove, as clearly illustrated in Fig. 2. The

tubes 36 just referred to constitute receiving 1 pockets into which the heavier materials fall, the accumulated materials being finally discharged from these pockets at the rear ends thereof, being understood that the tubes are open at both ends.

Plungers 37 are mounted to work 111 the forward ends of the receiving pockets or tubes, one plunger being provided for each tube and arranged and operated as illustrated in Fig. 3 where it will be seen that a slotted bell crank lever 38, fulcrumed on a support 39' secured to the forward side of the box or casing 26, operatively connects the rod or stem of the plunger with a link '40 engaging an arm 41 carried by the bottom of the bellows 27. It will thus be seen that as the bellows is alternately inflated and deflated the bell crank levers 38 will be correspondingly rocked, which latter in turn effects the desired reciprocation of the plungers 87 Within the receiving pockets 36 to force the particles of gold or other accumula'tled .material through the tubes and dischargethe same from the concentrator.

have herein illustrated a specific o m- 0f appar us a a l of C g y v invention into practical efl'ect, it is obvious tliatthe, invention is capable of embodiment tofreciprocate in the tube to force the concentrate from the tube, a bell crank, one arm ofwhich is secured to said plunger, a su 3- port secured to the casing on which t e bell crank 1s mounted, and means for reciprocatingsaid bellcrank from the bellows mechanism.
